To all whom it 7a2/(Ly concern:

e it known that I, JOSEPH W. WILSON, of

Brookville, in the county of Saline and State of Kansas, have invented certain new and useful. Aimprovements in Feed-Regulators for Roller-Mills, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in which- Figure l is a vertical section (on the line l l, Fig. 2) of afour-rollerinill with myinvention applied thereto, the feed-regulator for one pair of rolls being shown in vertical section and the other in side elevation. Fig. 2 is a horizontal section on the line 2 2, Fig. l, of a roller-1nill with my invention applied. Figs. 3 and 4 are vertical sections of the feed-regu later, on the lines 3 3 and 4 4', Fig. l, respectivel-y.

This invention relates to devices for regulating the supply of material to the: crushing-rolls of mills; and it consists in certain features of novelty, hereinafter particularly pointed out in the claims, being first fully described with reference to the accompanying' drawings, in which similar letters represent like parts in the several figures.

A represents the frame of the roller-mill, and B the supply boxes or spouts (that may be secured to the frame by any suitable means) for the reception of the material which enters at the opening ll at the top, and it descends is spread by adjustable defiectors C. The said deiiectors have pivots C', supported by the front and rear walls of the supplyspout, on which they turn, and may be adj usted and set to any required inclination by thumb-screws C2. The pivots C are situated at a point between the upper and lower edges of the valves and at. such distances from the sid/e walls of' the box and fromv each other that when turned to such positions that their upper (or lower) edges will have contact with each other their lower (or upper) edgesl will have contact with t-he side walls of the spout B. In the drawings the pivots are shown situated equidistant from the upper and lower edges of the delieetors and at equal distances from the end walls of the spout,\the distance between the` pivots themselves being exactly .double the distance between oneof them and the side wall nearest thereto.

yoke being formed separately and attached thereto by screws, bolts, or other suitable means. It is necessary that these rods should be flexible, otherwise (being fixed at both ends) the eccentric could not rotate nor could the shoes be adjusted vertically. ln order to permit the former operation, the yoke must be moved vertically, and in order to permit the latter operation the extremities of said 7o rods must move vertically. The studs or pins K are fixed to the shoes and fit loosely at their outer extremities in eyes formed at the extremities of the rods H.

The shaft I turns in bearings J, supported vby bracket-arms, (not shown and may be ro tated by belts, whose position is indicated by dotted lines at L, and which work on pulleys M, and on adjustable pulleys or tighteners, whose position is indicated by dotted circle at N, and'upon a shaft, whose position is indicated by dotted circle at O.

I have described my invention in connect-ion with a 4double roller-mill; but I do not confine myself to it-s use on such mill alone, at it is evident. that it can be advantageously used in connection with single mills without changing the essential features of my invention. l

I do not herein claim the subj ect-matter cov- '9c ered by my application for Letters Patent. Serial No. 267,390, filed March 16, 1888.

Having thus described my invention, the following is whatI claim as new therein and desire to secure by Letters Patent:v

l. The combination, with a pair of vibratory shoes D D, of a shaft I, and eccentricl, near each extremity of said shaft, and a pair of flexible rods, each having at an intermediate point a yoke embracing one of said ecroo centrics and each rod connected at its ends to the respective shoes.

' 2. Afeeding device for roller-mills, consisting of the supply-box B, having feed-opening B', the deflectors C, having pivots C', by which 1o 5 they are journaled within the supply-box, the thumb-nuts C2, by which the deflectors are adjusted to the desired inclination, the valve R, having serrations or teeth R and mounted on the front side of the supply-box and form- 1ro ing the lower edge of the side, thumb-nuts S, by which the valve is adjusted in keeping with the position of the detlectors, the Shoe D, the spring-rod E, and nuts E', supporting one end of the shoe, and the rods G, having collars G3, the springs G2, and thumb-nuts G', supporting the other ,end of the shoe, substantially as described. i

4l'which is itself vertically adjustable. The

shoe shown in my patent, No. 314,552, is not vertically adjustable.

It is. evident that the rapidity with which 5 the material is fed to the rolls will depend to a certain extent upon the positions of these valves; b ut this is not the function which they are especially designed to fulfill. They are intended more particularly as eveners or ro distributers for breaking up lumps, which result from dampness and distributing the material evenly and uniformly over the bottom of the shoe. For this purpose they should be within a, certain distance from the floors 15 of the shoes, whatever may be the inclination of the said iloors. 'For causing a faster feed the hangers are adjusted so as to increase the slope of the floors of the shoes,

the valves R being lowered to a corresponddepends to quite `a considerable extent upon vthe extent of thel surface, of the iio'or of the. shoe over which it travels after it passes the serrated or comb-toothed valve. In my patz 5 en t, No. 314,552, the front side of the spout to which the serrated valve is secured is very close to the edge of the shoe. I now prefer to construct the spout of much less width, so that a considerable portion of the iioor of evenness 1n the grain or other material resting upon the floor, caused by the teeth of the valve, being entirely shaken down as the grain slowly travels toward the outer edge of surface .the shoe is made to extend as far over the rolls as possible.

In the drawings the shoes are shown of such width that the grain falling therefrom .and to prevent its passing said rolls on the outside I secure to the inside of the casing deiiectors P, which catch the grain and return it to such point that it will be carried by 45 the moving surface of the outer roll into the spaces between them.

I represents a shaft which extends through 'the machine from end to end parallel with the rolls, and I I eccentrics* secured thereto 5o near its respective ends. Each of these eccentrics is embraced by a yoke or strap H, situated about midway between the extremities of a flexible rod H, whose extremities are connected with the respective shoes D by' 5 5A means of studs, pins, or bolts K', working through slotsK in the casing.
